The BigMeow is a larger version of the MeowMaid found in Super Paper Mario, where they are only found in Chapter 3-4. There are only two BigMeows in Fort Francis, and both of them are found in Francis' private rooms. They are invincible, and won't actively attack Mario and his friends, but the player can still take damage by touching them. Avoiding them is difficult, as the rooms they are found in are rather small compared to their large size.

They can be used to reach the ledges with the keys to Francis's room, as jumping on their heads can provide a helpful boost up to the ledge.
